I've run redrilled wheels and ones using wobble bolts, both are fine. I avoided the redrill route for my RPF1s because the market for redrilled wheels is small and I would have taken a large hit with it.
Who did you buy the wobble bolts from?
Edit: If you wanted to avoid redrilling, I can lend you my wobble bolts that definitely worked before to make sure it's not the wheels that are defective. Just pay for shipping and return shipping.
It's up to you really. Mine are conical as well and made by Bimecc. Just giving you an option to see if it may be the wheels that may be defective instead of the bolts.
